Intermittently Slow Downstream. Upstream unaffected.

Intermittently Slow Downstream. Upstream unaffected.

Can someone interpret potential issues from the tables I'm including?

Spectrum user here in Raleigh, NC.

200 down 20 up package. (maybe 10 up, idk);

This is the first time the downstream via speedtests has gone from ~200 Mbps to anywhere from ~1 Mbps to no higher than ~6 Mbps. Upstream never effected--stays consistently around ~10 Mbps (I believe that's what I pay for...)

I've been in this house less than 1 month and the internet service here is only about 2 weeks in. Oddly enough, at the apartment I was in prior, the same thing would happen. Granted, I had a different modem/router then than now, it was still always the same symptoms. ~100 Mbps maxx package dipping to no more than ~5 Mbps... Would come back to life days later or sometimes when I cave, call tech support, and they "resend lost signals" to my modem. (Apparently they got my modem stuck permanently in recovery mode when we moved to this house.)

I'm running an AC1900 modem/router. Signal logs below:

*Note: I'm phishing for input and items to discuss with the tech that is already scheduled to come out tomorrow (Feb. 4, 2018) for this issue. * Thank you in advance!
